BROOCHHPIN.

SPECIFICATION forming part of Letters Patent No. 373,482, dated November 22,1887.

Application tiled August 13, 1887.

To aZZ whom it may concern,.-

Be it known that I, JOHN H. Funny, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements Brooch-Pins, of which the f'ollowing is a description, reference being had to the accompanying drawings; forming a part of this specification, in which- Figure l is a bottom view in perspective of a brooch, showing my improvement; applied thereto. Fig. 2 is a longitudinal sectional view in detail of the pinhingc. Fig. 3 is a perspectiveviewin detail of the hinge-butt.7 Fig. 4 is a perspective view of the pin as it appears when ready for insertion in the butt; and Fig. 5 is atransverse sectional view taken upon the line :c x, Fig. 2, viewed in the direction as indicated by the arrow there shown.

Like letters ot' reference indicate like parts in the different figures.

A very important end to be attained in attaching pins to brooches is to retain the stift'- ness of the pin at the shank. This has been heretofore impracticable forl the reason that the heat imparted to the pin consequent upon soldering it to the hinge or butt draws the temper and softens the pin, thereby rendering it weak and pliable. My object is to overcome this obj ection by fastening the pin shank to the butt wit-hout the use ot' solder, while the fastening by which said shank is secured may also serve as a hinge.

To this end my invention consists in constructing a double socketed butt in the form of a cross, so that the axis of one socket may cross that of the other, thereby enabling the hingerivet to intercept and pass through a perforation or engage with a notch in the pinshank, allof which ishereinafter more particu larly described and claimed.

In the drawings, A represents an ordinary brooch, to which the joint B is soldered or otherwise rigidly attached in any well-known Way.

O represents a hinge-butt or shank-receiver, preferably made in one piece and having bores c c', the axes oi' which are arranged in parallel planes, but at right angles to each other, and so placed that one shall partially intercept the other, as indicated in Figs. 2 and 5.

Serial No. 246,821. (No model.)

D represents my improved brooch pin, which is sharpened at one end, as usual, but left of an indefinite length, so as to be long enough to meet the requirements of brooehes of varying length.

In fitting the pin to the brooch the shank is first inserted Within the bore or socket c and allowed to protrude sufiiciently to permit the point of the pin to be brought to the proper position. The pin is then marked to indicate its position inthe socket,when it is withd rawn and a notch, d, Figs. 2 and 4, formed therein coincident with the bore o. Said pin is then reinserted in said socket with the notch opposite to and coinciding with said bore c, when the butt O is placed in position in thejoint B and apintle or rivet, b, projected through the bore of said joint B and through the bore c, thereby engaging the notch d and securingthe pin D permanently in place. The surplus length ot pin projecting at the rear may be cut ot't either before or after its final insertion.

By this means it is obvious that the hardened temper of the pin-shank may be retained, while the pins may be adjusted to fit brooches of varying size. The various advantages of said construction are too obvious to require mention.

Having thus described my invention, I claim-- l. As a new article of manufacture, ahingebutt for broochcs, consisting of a piece of metal having cylindrical bores the axes of which are arranged substantially at right angles and which partially intersect with cach other, whereby a straight pin inserted in the one and having a notch arranged to coincide with the other may be retained in position by means of a rivet inserted in the other and engagingsaid notch, substantially as shown and described.

2. The combination of the butt O, having the intersecting bores c o', a pininsertedin the bore o', and having a notch arranged to coincide with a rivet and the usual hinge-joint of a brooch, substantially as show n and described.
